Bernard Kwabi-Addo, PHD (He)

Associate Professor

  • Biochemistry
  • College of Medicine


I am a Professor of Biochemistry and Molecular Biology and also a Principal Investigator of Prostate Cancer Research at Howard University, in Washington D.C. My research interests are: Molecular Biology/ biochemistry: Cancer Health Disparities, Signal Transduction, Gene Expression and Regulation, Epigenetic DNA methylation studies and Prostate Cancer Research. The focus on my current research activity is to elucidate aberrant epigenetic alterations that underlies prostate cancer etiology and the disease aggression, a disease that disproportionately impact men of African Ancestry. The ultimate goal of my research work is to identify novel epigenome-derived markers that can be used either alone or in conjunction with current molecular markers for screening and diagnosing prostate cancer disparity. I am also interested in understanding the social determinants and environmental factors and how these impact the genome to drive not only prostate cancer but cancer in general and cancer disparities. I give didactic lectures on various biochemistry and molecular biology topics to medical, dental and graduate students at Howard University. In my spare time, I educate local communities and church settings on topics of cancer prevention and the importance of adhering to the recommended age-appropriate screening as well as the importance of healthy dietary patterns, avoidance of sedentary lifestyle and the adoption of healthy behavior and lifestyle patterns to avoid and even reverse or eliminate chronic diseases.

I am an  Associate Professor of Biochemistry and Molecular Biology and a Principal Investigator of Prostate Cancer Research at Howard University Cancer Center. I have expertise in biochemical and molecular biology skills relevant fcto ncer research and health disparities. The current focus on my research laboratory is to elucidate aberrant global and loci-specific epigenetic alterations associated with aggressive prostate cancer in African American men. The goal of my laboratory is to identify novel epigenetic-based biomarkers for cancer detection and to explore epigenetic alterations in cancer for novel therapuetic angles.
